Table 1 Effects of sub-watersheds, landscape positions, and land use on plant biomass production and biomass export

From: Sustainable land management interventions lead to carbon sequestration in plant biomass and soil in a mixed crop-livestock system: the case of Geda watershed, central highlands of Ethiopia
